OXFORD East's MP joined a doctor on a training run as he geared up to complete his third marathon in a month.
Anneliese Dodds took part in a short training run with Alex Langford in South Park on Sunday - a day ahead of the Milton Keynes marathon yesterday.
Mr Langford is completing 270 miles worth of races - including four marathons and three ultra-marathons - to raise funds for Papyrus, a charity working to prevent suicide. He hopes to raise £5,000.
Ms Dodds, a keen runner herself, said it was a 'truly heroic mission'.
